Overmoulding of PC/ABS compounds
From Elastocon TPE Technologies, Inc. comes the STK 40 and STK 60 range of TPEs that are said to overmould easily and with excellent adhesion onto PC/ABS compounds.
The TPEs can enhance, improve, provide added protection or sound or vibration dampening, or otherwise complement a variety of consumer and industrial end products made of these PC or PC/ABS blends. Further, the low hardness (40 and 60 Shore A respectively) gives the products a soft touch or feel.
In addition to being suitable for overmoulding or co-extrusion applications, the TPE grades can be extruded, blow moulded or compounded. The STK series also has excellent colourability.
The company cites a list of PC/ABS compound brands where the new STK series of TPEs are claimed to have excellent overmould capabilities. Among them are LNP Faradex, Bayblend, 4Loy, Diablend, Durolux, Elastablend, Greenloy, Nexalloy, Polyblend, Hytex, Triloy, etc.
Faradex compounds are used for EMI/FI attenuation to provide electromagnetic and radio frequency interference in enclosures and components for business and medical equipment and optical instrumentation. Other PC and PC/ABS blends and PC alloys are used for appliance housings, mechanical parts for computers and service equipment and diagnostic equipment.
